PETER KELLER, OF CHICAGO, ILLINOI GAS-REGULATING DEVICE.

To all w/w/n it may concern Be it. known that 1, PETER KELLER, a citi-Zen of the United States, residing at the city of Chicago, in the countyof Cook and Shit-ate of Illinois, have invented a new and usefulImprovement in Gas-Regulating vices, of which the following is aspecification.

My invention relates to devices for regulating the flow of gas from aservice pipe and causing the same to he delivered at the point ofconsumption at a uniform and usually reduced pressure.

By means of my invention I am able to produce a cheap, simple anddurahle device; o newhich is effective in operation and of almostuniversal application in all cases where gas is used for purposes ofheating or illun'iination. 1

The principles of my invention a e illustrated in the drawings, forminga part of this specification, in which- Figure 1 shows a horizontalsection; Fig. 2 is a similar section in perspective, and Fig. 3 is anelevation of the inlet end.

Further describing my invention with reference to the drawings: 1represents the side walls, and 2 the outlet end of an outer casing orshell. The outlet end consists of a plate, preferably integral with theside Walls and has a plurality of openings The valve chamber 4 is in theform of a truncated cone, having its smaller diameter adjacent to theoutlet end, and is formed by the converging walls of the casing. Apartition 5, having openings 6 is placed in the small end of saidchamber. It is of such size that, when placed in [)osltlOn shown, itwill be spaced from the outlet end, leav ing a packing chamber 7 whichshould he tilled with shavings 8 of steel or other metal. The inlet endof the casing is closed hy a -plate 9 having inlet openings 10, to thechamber 4. in the plate 9 and also in the partition within which arereceived the ends of a guide rod 11, the same heime practically on thelongitudinal aXis of the device. Mounted on the guide run is a valvehaving a stem 12 and a head if) placed transve sely of the valvechamber. Between the said valve and partition 5 isinterposed a spring ll adapted to hold thextreme end of the valve stem 12 in contact. withthe plate 9. The head should he circular, and it willhe There is acentral depression Specification of Letters Patent.

seen that an annular opening will he formed hetwcen the peripherythereof and the inner walls of the gas chamber, and that such annularopening will vary in size according to the position assumed hy the valveon the guide rod 9.

Upon mounting the described device in such a manner that it is connectedwith the service pipe at the large or inlet end and that the small endwill be connected with the stove, illuminating apparatus or system ofpiping, the flow of gas takes place in the direction of the arrow,passing around the valve head 13 and flowing through the openings (5 and3 to the point desired. Additional pressure, causing a more rapid flowof as through the annular opening causes the valve to advance with thegas currentagainst the resistance of the spring 14, thereby reducing theannular space between the valve head and the inside of the casing. Theflow of gas will be checked until the pressure thereof in the rear ofthe valve head decreases, allowing the spring to force the valveproportionally back. The strength of the spring should be properlyproportioned to the desired pressure and to the weight of the valvewhich should be very light and preferably made of aluminum.

This make a very sensitive regulator and a complete and positiveregulation will be attained.

It will further be noted that the device an he placed and in operationat any angle, requiring therefor slight modification or none at all. Thesteel shavings placed in the packing chamber 7 are very efficient inaiding the action of the valve and any otherwise slight variation inpressure is completely absorbed. This material is peculiarly adapted forthe purpose as it does not mat or lose its elasticity, is practicallyindestructihle, keeping in its original condition as placed for anindefinite time.

I claim:

1. Tu a gas regulating device, a casing having a valve ehamher uniformlytapered from the inlet end to the outlet end, a guide r d securedlongitudinally of said chamber. a valve within the chamhcr slidable onsaid rod, and means for resisting the mption ol said valve toward theoutlet end of the casing.

2. In a gas regulating device, a casing having a valve chamhcr uniformlytapered from the inlet end to the outlet end, a guide. rod secured inthe longitudinal 8X15 of said chamber, a valve Within the chamberslidable on said rod, and means for resisting the motion of said valvetoward the outlet end of the casing.

3. In a gas regulating device, a casing having a valve chamber uniformlytapered from the inlet end to the outlet end, a perforated partitionplaced transversely of said chamber, a guide rod placed longitudinallyin said chamber and supported at one end on said partition, means forsupporting said rod at the inlet end of said chamber, a valve slidablymounted on said rod, and spring interposed between said valve and saidtransverse partition.

4'. In a gas regulating device, a casing having a valve chamberuniformly tapered from the inlet end to the outlet end, a perforatedpartition placed transversely in said chamber, a perforated plate at theinlet end, a guide rod secured between said plates in the longitudinalaxis of the casing, a valve slidahle on said guide rod arid elasticmeans for causing said valve to seek inlet end of the casing.

In a gas regulating device, a casing having a chamber uniformlydecreasing in size in the direction of the gas flow, a valve head placedtransversely of said chamber, a stationary guideway upon which saidvalve head is slidably mounted, and means for causing said membernormally to seek the inlet opening.

0. In a gas regulating device, a casing having a chamber uniformlydecreasing in size in the direction of the gas flow, and a symmetricallyformed valve head slidably mounted in said chamber and ada ted normallyto seek the inlet opening an a guidewa y for said head to keep the samein axial alinem'ent with the Said chamber.

In witness whereof, I have hereunto subscribed my name this 12th day ofJune 1912, in the presence of two subscribin witnesses.
